Add additional Lua functions that make use of regular expressions to match against fully qualified property identifiers

- Making the GUI use the new function setPropertyValueSingle to not incur the overhead of compiling the regex
 - The default setPropertyValue Lua function uses a wildcard, which replaces a * with the correct regex (.*) for ease of use
 - The setPropertyValueRegex Lua function allows a full regular expression to be used
